Description

Bicycle frame folding unit

Technical field

The folding device technical field of bicycle is the utility model is related to, in particular to a kind of bicycle frame folding unit.

Background technology

Folding bicycle (folding bicycle) belongs to a classification of bicycle.General folded bicycle has vehicle frame folding Joint and standpipe folding joint are formed.By vehicle frame folding, by front and rear two-wheeled doubling together, it can reduce by 45% or so length Degree.Vehicle can be put into boarding case and folding bag after folding, and the boot of automobile.During folding also without , can be manually by car folding and expanding by external tools.After folding by seat bar as the strong point so that fold after can stand surely.Folding Folded bicycle carries, is easy to use comfortable, mature production technology.

At present, existing folding bicycle is generally comprised such as lower part：

1st, frame part：Vehicle frame is the most basic structure for forming bicycle, and the skeleton and main body of bicycle, other Part is all mounted directly or indirectly on vehicle frame.The structure type of frame part has a lot, but according to can be with using crowd It is divided into men's style vehicle frame and the major class of woman style vehicle frame two.Vehicle frame is typically using normal carbon copper pipe by welding, combining.In order to subtract Light weight, improves intensity, and the bicycle of higher gears is manufactured using aluminium-alloy pipe.In order to reduce the resistance of fast running, some is certainly Driving also uses fairshaped steel pipe.Because bicycle is the driving force and cycling technical ability by human body itself and travel, car Can frame becomes caused shock loading and comfortably, safely deliver the important knot of human body under steam to bear bicycle Structure body, the quality of the frame part accuracy of manufacture, safe, steady, the light and speed of rider will be directly affected.General spoke is Footpath, in order to mitigate gravity, also have and be made that both ends are big, middle small reducing spoke, also in order to reduce air drag by spoke It is made flat streamlined.

2nd, cover tire：Decorative pattern on cover tire is to increase the frictional force with ground.It is divided into a point soft-sided according to side tire is soft or hard Two kinds of tire and hard-edge tire.Soft-sided tire section is wider, can all wrap the inner tube of a tyre, and the area that lands is bigger, and earth-grasping force is strong, cover tire width Especially wide, decorative pattern is more deeply and the cross-country mountain region of adaptation is used, the suitable various roads traveling of energy, similar to mountain bike.Hard-edge tire is conducted oneself with dignity Gently, landing, area is small, and earth-grasping force is weaker, cover tire narrower width, and decorative pattern is shallower and uses with adapting to highway, but small with resistance, Travel the advantages that brisk, suitably travelled on flat road, similar to highway car.

3rd, pedal：Pedal is assemblied on the left and right crank of middle axle, is a dress that translation power is converted into rotatory force To put, during cycling, pedal force passes to pedal parts first, then by crank shaft rotating crank, axis, chain flywheel, Make rear wheel, so that bicycle advances.Therefore whether the structure of pedal parts and specification are suitable, will directly affect cyclist Put whether placement of foot suitable, can the driving of bicycle be smoothed out.Therefore it is required that foot-operated must all have foot-operated face, it is necessary to pacify It is complete reliable, there is certain non-skid property, rubber, plastics or metal material manufacture can be selected.

4th, front fork component：Front fork component is in front position in bicycle structure, and its upper end is connected with handlebar part, Frame part coordinates with front tube, and lower end coordinates with front axle part, forms the guidance system of bicycle.Handlebar and front fork are rotated, can So that front-wheel changes direction, the guide effect of bicycle is served.The stressing conditions category cantilever beam property of front fork component, therefore front fork Part must have the properties such as enough intensity.

5th, chain：Chain is also known as blockchain, roller chain, links on sprocket wheel and flywheel.Its effect is by crank, chain by pedal force Wheel is delivered on flywheel and trailing wheel, drives what bicycle rear turned, is advanced so as to provide power.

6th, sprocket wheel：Pedal force is delivered on chain by crank, is made of high strength steel, ensures that it reaches the drawing of needs Power.

7th, flywheel：Screwed is fixed on the right-hand member of rear axle within flywheel, keeps same plane with sprocket wheel, and pass through chain It is connected with sprocket wheel, forms the drive system of bicycle.Single freewheel and the major class of multistage flying wheel two can be divided into from structure.Single-stage Flywheel is also known as single sprocket chain piece flywheel, mainly keeps off several steel balls etc. zero by overcoat, flat gear and fuse, very heavy, very heavy spring, packing ring, silk Part forms.

8th, folded bicycle joint (folder)

Folding joint is the position of most critical on folded bicycle, and it bears the pressure from various aspects, so it must Very firm while easy to operate again, outward appearance has aesthetic.

At present, folder used by existing folding bicycle or folding electric bicycle, generally comprises two pieces of difference The pleated sheet or folded sheet that are connected with front vehicle fork and Rear frame, retaining mechanism, hinge etc., when needing locking, it is necessary to by two pieces Folded sheet is bonded in opposite directions, retaining mechanism is inserted in the groove for being used to lock of two pieces of folded sheets, in the screw thread by retaining mechanism Phase length is adjusted, finally again by the handle of closed and locked mechanism so that folding bicycle reaches locking, the side of locking Method bothers, and makes the folding process of folding bicycle cumbersome.
